An onboard diagnostic memory module is configured to plug into the OBD II port and has a real-time clock and power supply, a microprocessor powered from a standard OBD II port, microprocessor operating firmware, and an attached memory (7 MB). In operation, the onboard diagnostic memory module is preprogrammed with data collection parameters through microprocessor firmware by connection to a PC having programming software for the module firmware. Thereafter, the onboard diagnostic memory module is moved into pin connection with the OBD II port of a vehicle. Data is recorded on a &ldquo;trip&rdquo; basis, preferably using starting of the engine to define the beginning of the trip and stopping of the engine to define the end of the trip. Intelligent interrogation occurs by interpretive software from an interrogating PC to retrieve a trip-based and organized data set including hard and extreme acceleration and deceleration, velocity (in discrete bands), distance traveled, as well as the required SAE-mandated operating parameters.

Module for monitoring vehicle operation through onboard diagnostic port

A portable, pocket sized instrument for measuring wind speed and indicating wind direction wherein a multiple number of vanes of varying size and spacing are radially and orthogonally fixed to a disc and wherein the force of the wind against the vanes causes the disc to rotate against the restraining torque of a spring. Wind speed is indicated by angular rotation of the disc and wind direction is indicated by the orientation of the instrument at the time of maximum reading. A foldable handle protects the mechanism and increases the convenience of positioning the instrument.
